A drive axle of an electrically drivable vehicle including first and second drive wheels (R1, R2), first and second manual transmissions (G1, G2) and first and second electrical machines (EM1, EM2) which each have a respective drive shaft (1a, 1b). The first electrical machine (EM1) drives the first drive wheel (R1), via the first manual transmission (G1), and the second electrical machine (EM2) drives the second drive wheel (R2), via the second manual transmission (G2). The manual transmissions are each designed as three-speed transmissions (G1, G2) which have identical transmission ratios (i1, i2, i3).

An inter-axle differential assembly comprising a driving input shaft, a forward differential wheel, a rear differential wheel, a differential spider connected for common rotation with the input shaft and on which differential pinions configured to meshingly engage with said differential wheels are rotatably mounted, and a differential housing to which the differential spider is connected for common rotation. The assembly comprising an output wheel via which torque is transferable to a rear driving axle, and a connection means movable between: an open position which connects the output wheel to the rear differential wheel so that the differential housing can rotate independently of the rear differential wheel, a locking position connecting both of the differential housing and the output wheel to the rear differential wheel, and a disconnecting position connecting the differential housing to the rear differential wheel, so that the output wheel can rotate independently of the rear differential wheel.
